Title: Fault locating apparatus
IPC: G01R31/08
Filed: 1955-04-18
Abstract: 772,205. Electric tests. NORTHERN ELECTRIC CO., Ltd. April 18, 1955 [April 30, 1954], No. 11136/55. Class 37. In a fault resistance bridge guard electrodes at each end of the conductor under test prevent surface leakage currents from flowing through the bridge balance detector. In Fig. 2 there is a high resistance fault at 4 from core 1 through insulation covering 2 to metallic outer sheathing 3 and the D.C. fed bridge comprises (see also Fig. 5) ratio arms 7, 8 and arms 10, 11 formed by that portion of core 1 on either side of the fault 4. The ratio arms 7, 8 are controlled by balance tapping 9 calibrated in per cent distance to fault and detector 14 is in series with fault resistance 4. The guard rings 19, 20 surround the insulation covering 2 at the cable ends and are connected via leads 21, 22 to the variable tapping 9 so that at bridge balance guard rings 19, 20 are at the same potential as sheathing 3 whereby surface leakage currents 18, 19 flow into and out of guard rings 19, 20, i.e. across the ratio arms 7, 8 (see Fig. 5), and do not affect the balance detector 14. In the absence of guard rings 19, 20 leakage currents 13, 14 would flow through detector 14 (see Fig. 4) and the balance position of arm 9 would be false. The internal leakage current 15 is compensated by introducing a corrective factor into the reading given by balance tapping 9. The ratio arms 7, 8 are of appropriately low resistance so that 18, 19 do not substantially affect the balance potential.
